碩士 / 國立中央大學 / 應用地質研究所 / 97 / A reservoir is created by building a sturdy dam, filled by the stream, and formed an artificial lake. The water impoundment in an artificial lake will exchange with the environment, which is called hydrological effect of reservoir. There are ~50,000 large dams in the world, summation of their reservoir water capacity is ~6,500 cubic kilometers of freshwater, almost equal to half of the storage global freshwater lakes, cause a great change of terrestrial storage, and impact on global sea level rise should be expected.
By reconstructing the history of water impoundment in the world''s artificial reservoirs, a total of ∼10,000 cubic kilometers of terrestrial storage has been derived, reduced global sea level rise by -27.6 millimeters. Averagely, -0.43 millimeters per year of global sea level rise is estimated due to dams building during the past half century. The reconstructed global sea level history, accounting for the impact of reservoirs by adding back the surface and ground water impoundment, shows that global sea level rise at 20th century should be more then 20 centimeters, instead of 18 centimeters estimated without considering the effect of reservoir storage.
